IMPROVEMENT IN PAPER-TUBE MACHINES.

specification forming part of Letters Patent No. 169. [07, dated October 26, 1875; application filed October 1, 1874.

To all whom it may concern:

Be it known that I, NICE KEELY, of Leverington, in the county of Philadelphia, State of Pennsylvania, have invented an Improved Paper-Tube Machine, of which the following is a specification:

The object of my invention is, generally, to

provide a machine for the fabrication of uni-' form hollow cylindrical shells made up of several agglutinated convolute layers of paper, and, particularly, for the formation of the shell or body of a certain improved paper cask or other receptacle of which I am the inventor, and for which Letters Pa ent are pending.

Figure 1 of the annexed drawings represents a side elevation of my machine; Fig. 2, a plan of the same; Fig. 3, a medial longitudinal section; Fig. 4, a detached view of abisected hanger employed to support one end of the journal of the lower or former roll, hereinafter described. Fig. 5 represents a shell or body, a part in longitudinal section, of one of my improved 'casks as formed by the machine.

Like letters and figures, where they occur in the several drawings, refer to corresponding parts. 1

,My invention will be best understood by detailing in fullfthe 'modus operandi of its constituent mechanism from the coil of paper A on roller 0 to the final removal of the completed shell from the cylindrical former R. The continuous broad strip of paper m passes over the idle-roller D, and then horizontally beneath the cut-ofl' knife K onto the roll R, where its end is inserted in a slit, 8, traversing the length of the roll. R and B. are super-' imposed cylinders whose diameters are, identical with the inside diameter of the shell which it is proposed to form. They are geared together by the spur-wheels E E. The upper roll, 1t, is a calender-roll, plain and smooth, except in that it bears on and around its periphery, near either extremity, a screw-thread, T, Fig. 1, in high relief, corresponding to like in taglio threadslnot shown in drawings) placed in juxtaposition thereto in the' surface of the nether roll B. These threads, as the winding of the layers of paper around it proceeds, impress their fac-similes in the paper shell 4, as will appear by reference to Fig. 5. The free end of or having been introduced into slits, as

mentioned, R and R. are then rotated forward by means of handle H (for which a pulley is substituted when the apparatus is to be oper ated by power) untilthe slit, and consequently the end of strip m, is in a vertical line,-passing through the center-sot both the upper and lower rolls. The drawings represent the same in such position. 11?. is kept at proper tension by means of a brake or brakes, O, pressing on the flanges of roller G, and which are connected with and operated by a ratchet-winch, S, Figs. 1 and 3. The required degree of pressure on the paper 5 (and experience proves that considerable pressure is advantageous) as it winds on it is secured by weighting levers L, which bear, near their fulcrums, on the upper half of the journal-boxes of R. The shell, Fig. 5, being constructed of a certain number of congiutinated layers ofstrip m. each layer corresponding toa revolution of the rolls, it is necessary at a particular point in their revolutions to drop down the paste-box P, which carries the pasteapplying rollers'6 and 7, whereby the application of the paste shall temporarily cease. This movement occurs when It it have made half a turn less than is sufficient to complete the final layer of paperof each shell.

I shall now proceed to a description of the devices by the co-operation of which this-end at the proper periods is effected. A shifting ec-' centric-cam, J, located on shaft V of roll R, and slotted in order to slide over a spline on the same, is thrown in and out of position by means of a lever, N pivoted on a cross-piece in the frame of the machine.

In Fig. 2 the eccentric is represented out of position. \Vhen in position its face impinges, as it revolves, against the long arm of a lever, O, which oscillates about a fulcrum-pin fixed in the frame-work. O is held against the stop 9, or, when cam J rotates, against the face of the latter by means of a spring, f, with which 0 is connected by a cord, 0, or otherwise. The oscillation of 0, caused by the rotation of the cam, transmits motion to two connected pawls, p p, hinged to lever O, which advances a ratcheted rack, F. The ofiice of p is to move the rack. 19 is simply ancillary, keeping F in place while the former retreats into the next succeeding tooth.

F is provided at or near one end with a horizontal pin, a, which, as the former fis pushed on,comes incohttiritwith a vertical pinorstud, 31, inserted in one of a series of holes, 0 e, Fig. 2, in a sliding bar, W. [he distanceapart of.v e 0 corresponds with that of the teeth of rack F, conseqnentlyiwheny is placed, for example,- in the fifth hole, conntingironrtowardthe end of F, pin a; will strike against y on the fifth ievolution of shaft Yetha'tds to say ot' rolls R R. Now, the piece W has attached firmly thereto a second bar or rod, Z, endinginabevel catclnl which latchesin a slot, 7', shown in dotted lines, Fig. 1, in an uprie'ht, Ufto ward which Z is forced by a helical spring, q.

U is located directly beneath J when the'lat-- It! is in ,position, :J just escaping the end of thejnprig'htwhenfhjeld bycatclr b. It is also conneeted byarOc-k-b: r, t, with asecond par- ,allel upright, 3, which sipports platform Y, .nponwhichpaste box P is placed. When pin iscansed' to impinge {against stud y, catch b i'etreats from slot'r, and, asthechm moves on arbnnd tocoinplete its finalrevolntion, P

So soon as m isfsevered 1R and Iceman-[lei forward, whereby thepasting on brine remainder of the strip is accom- 5p]i neumi paste, it is clear, having already been ,applied tothe approaching semi pe riplie'ry of the shell when the paste-box Idropped. 1The tnlnilar shell, Fig.5, is now i ready; for thejattachmentot' one or more, as desired, strengthening bands, 10, pasted in ,successivelay 's by repetition of the'described operation of. forming the nainbody. uarrowstripsof imper j, from which these j jnforcihg bands are made, arejsiipplied ,fromh roller, l, around which they are coiled.

The shell is now ready to "be removed from R, which it. tightly embraces. In order to do thisthe layers otfpaper being compressed with considerable force into the intag'lio screw-thread on. B, it hecomes necessary to reduce thediaineter 0f the latter. u

A reference to the sectional View, Fig. 3,

will discover that R is provided with three movable sections, a b! h firmly, held to main body of the roll byasniany dovetail keys or wedges c d"e,constructed(as also are R and R) of iron, andniicelyfittedfin.
